Description

Technical Field

[0001] This application relates to the field of vibration equipment technology, and in particular to a vibration platform and casting production equipment. Background Technology

[0002] In the field of casting, after the material is injected, the mold needs to be vibrated to a certain extent to release air bubbles and allow the material to penetrate into every corner of the mold. Most existing casting vibration platforms use a vibration motor mounted on the bottom of the platform as the vibration source. Under long-term operation, because the vibration motor is constantly running under high load, its bearings, coils and other key components are prone to wear or overheating, leading to an increased equipment failure rate and requiring frequent shutdowns for maintenance or even motor replacement.

[0003] However, since the platform is usually fixed to the equipment base by bolts, brackets and other connecting components, the disassembly and assembly process of the vibration motor is extremely complicated. It not only requires the removal of multiple fasteners, but also alignment and correction, which consumes a lot of time and manpower and seriously affects the continuity of production line operations and overall efficiency. Utility Model Content

[0004] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a vibration platform and casting production equipment that can realize the rapid disassembly and replacement of vibration motors, greatly simplify the maintenance process, thereby effectively reducing equipment downtime and improving production efficiency.

[0005] This application provides the following technical solution: In a first aspect, embodiments of this application provide a vibration platform, which includes a vibration base, a vibration platform, at least one vibrator and at least one shock absorber, wherein the vibration platform is disposed above the vibration base and the vibrator is disposed on the vibration platform; The shock absorber includes an upper connector, a lower connector, and an elastic element. The upper connector is disposed on the vibration platform, and the lower connector is disposed on the vibration base. The upper connector has an upper insertion hole, and the lower connector has a lower insertion hole. The upper and lower insertion holes are arranged opposite to each other. One end of the elastic element passes through the upper insertion hole and abuts against the bottom wall of the upper insertion hole. The other end of the elastic element passes through the lower insertion hole and abuts against the bottom wall of the lower insertion hole. The upper and lower connectors are inserted into each other at their closest ends, forming an annular gap.

[0006] In some embodiments of the first aspect, the upper connector has a plug-in end, the upper insertion hole is located at the plug-in end, the plug-in end passes through the lower insertion hole, and the annular gap is formed between the plug-in end and the hole wall of the lower insertion hole.

[0007] In some embodiments of the first aspect, the shock absorber further includes a damping pad laid on the inner wall of the lower insertion hole, and the damping pad is located within the annular gap.

[0008] In some embodiments of the first aspect, the damping pad is an elastic pad that fills the annular gap.

[0009] In some embodiments of the first aspect, the shock-absorbing pad and the inner wall of the lower insertion hole are detachably connected.

[0010] In some embodiments of the first aspect, the sidewall of the upper connector has an upper inspection port, which is connected to the upper insertion hole; the sidewall of the lower connector has a lower inspection port, which is connected to the lower insertion hole; wherein the upper inspection port and the lower inspection port are located on the same side and are arranged opposite to each other.

[0011] In some embodiments of the first aspect, there are multiple vibrators, at least one of which is configured to generate vibration along the X-axis direction and at least one of which is configured to generate vibration along the Y-axis direction.

[0012] In some embodiments of the first aspect, the shock absorber further includes a clamping member and an adjusting member, the clamping member being located in the upper insertion hole and abutting one end of the clamping member and the elastic member, the adjusting member being disposed on the upper connecting member and connected to the clamping member, the adjusting member being used to adjust the distance between the clamping member and the vibration platform.

[0013] In some embodiments of the first aspect, the adjusting member includes a screw and at least two locking nuts, one end of the screw passing through a through hole in the tightening member and connected to the tightening member; the other end passing through a through hole in the vibrating platform, and at least one of the locking nuts being threaded to both ends of the screw, and the upper connecting member and the vibrating platform being clamped between two of the locking nuts.

[0014] Secondly, embodiments of this application also provide a casting production device, the casting production device including a vibration platform as described in any of the above embodiments.

[0015] The embodiments of this application have the following advantages: This application provides a vibration platform. During operation, a vibrator (such as a vibration motor) mounted on the vibration platform is activated, generating high-frequency mechanical vibration. This vibration is directly transmitted to the vibration platform, causing the mold placed on the platform to vibrate accordingly, thereby achieving the purpose of expelling air bubbles and uniformly filling materials. The vibration platform is connected to the vibration base below through multiple shock absorbers. The core of the shock absorber is an elastic element (such as a cylindrical spring), whose upper and lower ends are respectively inserted into the insertion holes of the upper and lower connectors and abut against the bottom wall of the holes. This makes the platform, elastic element, and base form an elastic support system, allowing the platform to vibrate as necessary while preventing the vibration from being directly and unbufferedly transmitted to the base and the ground, thus playing a role in vibration isolation and stability. The key lies in the insertion and engagement design of the upper and lower connectors. When it is necessary to replace or repair the vibrator, since the vibrator is mounted on the platform, it is only necessary to lift the entire vibration platform (along with the vibrator on it) upwards. During the lifting process, the upper connector rises accordingly, disengaging it from the insertion and engagement with the lower connector. Simultaneously, the upper end of the elastic element is pulled out from the upper insertion hole of the upper connector, and the lower end is pulled out from the lower insertion hole of the lower connector. At this point, the vibration platform is completely removed, making it extremely convenient to maintain or replace the vibrator fixed on the platform. After maintenance, the platform is lowered, the upper and lower connectors are realigned and reconnected, and the elastic element automatically returns to its upper and lower insertion holes, allowing the platform to resume operation.

[0016] Therefore, the core benefit of this application is the rapid disassembly and maintenance of the vibration motor. Through a clever plug-in shock absorber design, the traditional cumbersome process requiring the removal of numerous bolts is eliminated. Maintenance personnel no longer need to use tools to loosen fasteners one by one; they can simply lift and lower the platform to disassemble and install the vibrator. This greatly simplifies the maintenance process, transforming complex mechanical operations into simple hoisting work. Furthermore, it significantly reduces equipment downtime, improves production efficiency, and the rapid disassembly and assembly process shortens the previously time-consuming process, effectively reducing production line downtime. This ensures the continuity and overall efficiency of casting production operations, which is of great significance for large-scale industrial production. Additionally, the simplified operation reduces the skill requirements and labor intensity for professional maintenance personnel, saving considerable time and manpower. It avoids problems such as thread stripping and component damage that may result from frequent bolt removal, extending the service life of related connecting components and reducing overall maintenance costs. Moreover, the elastic element of the shock absorber ensures that the platform has good elasticity and cushioning performance during operation, ensuring efficient transmission of vibration energy to the mold while effectively isolating vibrations. The annular gap formed when the upper and lower connectors are inserted provides the necessary margin of movement for the platform during vibration, preventing rigid collisions or jamming, and ensuring the smoothness and reliability of the vibration process.

[0026] In related technologies, in the field of casting molding, after material is injected, the mold needs to be vibrated to a certain extent to release air bubbles and allow the material to penetrate into every corner of the mold. Most existing casting vibration platforms use a vibration motor mounted on the bottom of the platform as the vibration source. Under prolonged operation, the vibration motor operates under high load, making its bearings, coils, and other key components prone to wear or overheating, leading to increased equipment failure rates and requiring frequent shutdowns for maintenance or even motor replacement. However, since the platform is usually fixed to the equipment base via bolts, brackets, and other connecting components, the disassembly and assembly of the vibration motor is extremely cumbersome. It requires disassembling multiple fasteners and alignment adjustments, consuming significant time and manpower, severely impacting the continuity and overall efficiency of the production line.

[0027] As shown in Figure 1, Figure 2 and Figure 3As shown, to solve the above-mentioned technical problems, this application provides a vibration platform. The vibration platform includes a vibration base 300, a vibration platform 100, at least one vibrator 200, and at least one shock absorber 400. The vibration platform 100 is disposed above the vibration base 300, and the vibrator 200 is disposed on the vibration platform 100. The shock absorber 400 includes an upper connector 410, a lower connector 420, and an elastic member 430. The upper connector 410 is disposed on the vibration platform 100, and the lower connector 420 is disposed on the vibration base 300. The upper connector 410 has an upper insertion hole, and the lower connector 420 has a lower insertion hole. The upper and lower insertion holes are arranged opposite to each other. One end of the elastic member 430 passes through the upper insertion hole and abuts against the bottom wall of the upper insertion hole. The other end of the elastic member 430 is provided with a lower insertion hole and abuts against the bottom wall of the lower insertion hole; and the upper connector 410 and the lower connector 420 are inserted into each other at their close ends and form an annular gap 440.

[0028] In these embodiments, the vibrating stage 100 is disposed above the vibrating base 300, and the two are elastically connected by a shock absorber 400. The vibrator 200 is directly disposed on the vibrating stage 100 and is used to drive the vibrating stage 100 and the mold above it to vibrate, so as to facilitate the venting and filling of the casting material.

[0029] The shock absorber 400 in this embodiment is one of the key components for enabling quick replacement of the vibration motor. Each shock absorber 400 includes an upper connector 410, a lower connector 420, and an elastic member 430.

[0030] The top of the upper connector 410 is fixed to the bottom surface of the vibration stage 100 by welding or bolts. The upper connector 410 has an upper insertion hole in its central axis. This upper insertion hole is a blind hole with a flat bottom wall.

[0031] The bottom of the lower connector 420 is fixed to the top surface of the vibration base 300 by welding or bolts. The lower connector 420 has a lower insertion hole in its central axis. This lower insertion hole is also a blind hole, and its bottom wall is flat.

[0032] The elastic element 430 is a helical compression spring. One end of the spring passes through the upper insertion hole of the upper connector 410 and directly abuts against the bottom wall of the upper insertion hole. The other end of the spring passes through the lower insertion hole of the lower connector 420 and directly abuts against the bottom wall of the lower insertion hole. It should be noted that the elastic element 430 provides elastic movement allowance between the upper connector 410 and the lower connector 420, that is, the upper connector 410 can move up and down.

[0033] In the assembled state, the upper connector 410 and the lower connector 420 are axially engaged at their closest ends (i.e., the ends with the insertion holes). Specifically, a clearance fit or transition fit is formed between the outer circumferential surface of the upper connector 410 and the inner circumferential surface of the lower connector 420, allowing them to be coaxially aligned and slide relative to each other. Because the upper connector 410 and the lower connector 420 have different diameters and a certain axial overlap, an annular gap 440 is formed between them radially after they are engaged. The presence of this annular gap 440 allows the shock absorber 400 to have a certain displacement buffering capacity when subjected to lateral forces, while avoiding rigid friction between the metal parts.

[0034] In this embodiment, the number of vibrators 200 can be one, two, or more, and their installation position on the vibration table 100 can be adjusted according to the center of gravity of the mold and the required vibration mode. The vibrators 200 can be detachably installed on the vibration table 100 via flange connection, bolt connection, or snap-fit ​​structure to further improve the changeover speed.

[0035] The elastic element 430 can also be replaced by other elastic materials such as rubber pads or air bladders, as long as it can achieve contact between its two ends and the bottom walls of the upper and lower insertion holes respectively. The dimensions of the annular gap 440 can be designed according to the actual vibration damping requirements and the allowable displacement.

[0036] Therefore, this application provides a vibration platform. During operation, a vibrator 200 (such as a vibration motor) mounted on the vibration platform 100 is activated, generating high-frequency mechanical vibration. This vibration is directly transmitted to the vibration platform 100, causing the mold placed on the platform to vibrate accordingly, thereby achieving the purpose of expelling air bubbles and uniformly filling materials. The vibration platform 100 is connected to the vibration base 300 below through multiple shock absorbers 400. The core of the shock absorber 400 is an elastic element 430 (such as a cylindrical spring), whose upper and lower ends are respectively inserted into the insertion holes of the upper connector 410 and the lower connector 420, and abut against the bottom wall of the hole. This makes the platform, the elastic element 430 and the base form an elastic support system, which allows the platform to vibrate as necessary, while avoiding the vibration being directly and unbufferedly transmitted to the base and the ground, thus playing a role in vibration isolation and stability. The key lies in the insertion and mating design of the upper and lower connectors 420. When the vibrator 200 needs to be replaced or repaired, since the vibrator 200 is mounted on the platform, simply lift the entire vibrating platform 100 (along with the vibrator 200 on it) upwards. During the lifting process, the upper connector 410 rises accordingly, disengaging from its insertion into the lower connector 420. Simultaneously, the upper end of the elastic element 430 is pulled out from the upper insertion hole of the upper connector 410, and the lower end is pulled out from the lower insertion hole of the lower connector 420. At this point, the vibrating platform 100 is completely removed, making it extremely convenient to maintain or replace the vibrator 200 fixed on the platform. After maintenance, lower the platform, realign and reconnect the upper and lower connectors 420, and the elastic element 430 automatically returns to its upper and lower insertion holes, allowing the platform to resume operation.

[0037] Therefore, the core benefit of this application is the realization of rapid disassembly and maintenance of the vibration motor. Through the ingenious plug-in shock absorber 400 design, the traditional cumbersome process requiring the removal of numerous bolts is eliminated. Maintenance personnel no longer need to use tools to loosen fasteners one by one; they can simply lift and lower the platform to complete the disassembly and installation of the vibrator 200. This greatly simplifies the maintenance process, transforming complex mechanical operations into simple hoisting work. Furthermore, it significantly reduces equipment downtime, improves production efficiency, and the rapid disassembly and assembly process shortens the previously time-consuming process, effectively reducing production line downtime. This ensures the continuity and overall efficiency of casting production operations, which is of great significance for large-scale industrial production scenarios. Additionally, the simplified operation reduces the skill requirements and labor intensity for professional maintenance personnel, saving considerable time and manpower. It avoids problems such as thread stripping and component damage that may result from frequent bolt removal, extending the service life of related connecting components and reducing overall maintenance costs. Furthermore, the elastic element 430 of the shock absorber 400 ensures that the platform has good elasticity and cushioning performance during operation, ensuring that vibration energy is efficiently transferred to the mold while effectively isolating vibration. The annular gap 440 formed when the upper connector 410 and the lower connector 420 are inserted provides the necessary range of motion for the platform during vibration, preventing rigid collisions or jamming, and ensuring the smoothness and reliability of the vibration process.

[0038] In some embodiments, the upper connector 410 has a plug-in end, an upper insertion hole is located at the plug-in end, the plug-in end passes through the lower insertion hole, and an annular gap 440 is formed between the plug-in end and the hole wall of the lower insertion hole.

[0039] In these embodiments, the top of the upper connector 410 is fixed to the bottom surface of the vibration stage 100 by welding or bolting. The lower part of the upper connector 410 has a plug-in end, which is a cylindrical boss. An axially extending upper insertion hole is provided at the axis of the plug-in end. The upper insertion hole is a blind hole with a flat bottom wall.

[0040] The bottom of the lower connector 420 is fixed to the top surface of the vibration base 300 by welding or bolts. The lower connector 420 has an axially extending lower insertion hole in its center axis. The lower insertion hole is either a through hole or a blind hole, and its bottom wall is flat.

[0041] In this embodiment, the elastic element 430 is a helical compression spring. One end of the spring passes through the upper insertion hole of the upper connector 410 and directly abuts against the bottom wall of the upper insertion hole. The other end of the spring passes through the lower insertion hole of the lower connector 420 and directly abuts against the bottom wall of the lower insertion hole.

[0042] In the assembled state, the insertion end of the upper connector 410 passes through the lower insertion hole of the lower connector 420, achieving an axial insertion fit between the upper connector 410 and the lower connector 420. Specifically, the outer circumferential surface of the insertion end and the wall of the lower insertion hole adopt a clearance fit, forming an annular gap 440 between them. This annular gap 440 allows the shock absorber 400 to have a certain radial displacement buffering capacity when subjected to lateral forces, preventing jamming or stress concentration caused by minor misalignment during vibration, and ensuring the smoothness and reliability of the vibration process.

[0043] like Figure 3 As shown, in some embodiments, the shock absorber 400 further includes a damping pad 450, which is laid on the inner wall of the lower insertion hole and is located within the annular gap 440.

[0044] The key improvement in this embodiment is that a damping pad 450 is laid on the inner wall of the lower insertion hole. The damping pad 450 is made of a flexible material (such as polyurethane, rubber or nylon), and its thickness is precisely designed so that when the insertion end of the upper connector 410 is inserted into the lower insertion hole, the damping pad 450 is exactly located within the annular gap 440 between the outer wall of the insertion end and the inner wall of the lower insertion hole, and forms a slight interference fit or tight contact with the outer wall of the insertion end.

[0045] The damping pad 450, located within the annular gap 440, forms a flexible buffer layer between the plug-in end and the lower insertion hole. This effectively reduces friction and wear when the metal parts (plug-in end) are in direct contact with the metal hole (lower insertion hole), thus reducing operating noise. When the vibrating platform 100 experiences radial swaying, the damping pad 450 absorbs some of the radial vibration energy, improving the platform's operational stability. It also prevents damage to the metal hole walls or plug-in end surfaces caused by long-term vibration, extending the overall service life of the shock absorber 400.

[0046] For example, in this embodiment, the material of the shock-absorbing pad 450 is not limited to polyurethane, rubber, or nylon, but can also be other polymer materials with elasticity and wear resistance. The shock-absorbing pad 450 can be a one-piece annular bushing or it can be composed of multiple arc-shaped blocks spliced ​​together. Its thickness and hardness can be optimized according to the platform's load and vibration frequency.

[0047] Furthermore, the installation position of the damping pad 450 can also be varied. For example, the damping pad 450 can be placed on the outer peripheral surface of the plug end, rather than on the inner wall of the lower plug hole, as long as flexible contact can be formed within the annular gap 440. Alternatively, damping material can be placed on both the outer wall of the plug end and the inner wall of the lower plug hole to obtain a stronger cushioning effect.

[0048] In some embodiments, the damping pad 450 is an elastic pad that fills the annular gap 440.

[0049] The key improvement in this embodiment is that the shock-absorbing pad 450 is an elastic pad made of a highly elastic material (such as polyurethane, natural rubber, or silicone). This elastic pad is designed to fill the annular gap 440 between the insertion end of the upper connector 410 and the lower insertion hole of the lower connector 420. In the assembled state, the elastic pad fits tightly against the inner wall of the lower insertion hole, and its inner circumferential surface is in interference fit or close contact with the outer circumferential surface of the insertion end, thereby substantially filling the entire annular gap 440.

[0050] Because the elastic pad fills the annular gap 440, it forms a flexible constraint on the insertion end in the radial direction. When the vibration platform 100 experiences slight radial displacement or swaying during operation, the elastic pad can effectively absorb these non-axial vibration energies, providing strong buffering force and significantly improving the smoothness and stability of the platform operation.

[0051] The elastic pad completely separates the metal connector from the inner wall of the lower insertion hole, thus completely avoiding direct friction, collision and wear between metals, greatly reducing operating noise and extending the service life of the shock absorber 400.

[0052] The filled elastic pad can also play a certain role in dust prevention, preventing external impurities from entering the mating area and keeping the mating surfaces clean.

[0053] In some embodiments, the shock-absorbing pad 450 and the inner wall of the lower insertion hole are detachably connected.

[0054] In these embodiments, since the damping pad 450 is a consumable, the detachable connection facilitates replacement. For example, the damping pad 450 is adhered to the inner wall of the lower insertion hole.

[0055] like Figure 3 As shown, in some embodiments, the sidewall of the upper connector 410 has an upper inspection port 411, which is connected to the upper insertion hole. The sidewall of the lower connector 420 has a lower inspection port 421, which is connected to the lower insertion hole. The upper inspection port 411 and the lower inspection port 421 are located on the same side and are arranged opposite to each other.

[0056] In these embodiments, an upper inspection port 411 is provided on the side wall of the upper connector 410. The upper inspection port 411 is a through hole or groove that penetrates the side wall radially, and one end of it is connected to the upper insertion hole, so that the inside of the upper insertion hole can be observed from the outside through the upper inspection port 411.

[0057] A lower inspection port 421 is provided at a corresponding position on the side wall of the lower connector 420. The lower inspection port 421 is also a radial through hole or groove, one end of which is connected to the lower insertion hole, allowing external observation of the inside of the lower insertion hole.

[0058] In the assembled state, the upper inspection port 411 and the lower inspection port 421 are located on the same side of the upper and lower connecting parts 420 and are arranged opposite each other. When the upper and lower connecting parts 420 are correctly aligned, the upper inspection port 411 and the lower inspection port 421 are aligned axially, forming a continuous observation channel. Through this observation channel, the operator can directly visually inspect whether the spring is fully inserted into the upper and lower insertion holes and correctly abuts against the bottom wall of the hole, avoiding the risk of insufficient preload or falling off due to improper installation. When raising or lowering the platform for maintenance, the inspection port can be used to help determine whether the upper and lower connecting parts 420 are aligned, ensuring a smooth insertion process and enabling internal maintenance and adjustment.

[0059] In this embodiment, the upper inspection port 411 and the lower inspection port 421 can be circular, rectangular, or elongated, and their size should be such that the bottom of the socket can be clearly observed. One or more inspection ports can be provided, preferably located on the side that is easy for the operator to observe.

[0060] In some embodiments, there are multiple vibrators 200, at least one vibrator 200 is configured to generate vibration along the X-axis direction, and at least one vibrator 200 is configured to generate vibration along the Y-axis direction.

[0061] One of the key improvements in this embodiment is that there are multiple vibrators 200, which are differentiated to generate vibrations in different directions.

[0062] At least one vibrator 200 is configured to generate vibration along the X-axis. For example, a vibration motor is mounted with its vibration axis parallel to the X-axis, so that it primarily excites the stage to generate reciprocating vibration in the X-axis direction.

[0063] At least one vibrator 200 is configured to generate vibration along the Y-axis. For example, another vibration motor is mounted with its vibration axis parallel to the Y-axis, so that it primarily excites the stage to generate reciprocating vibration in the Y-axis direction.

[0064] With this configuration, the vibrating stage 100 can simultaneously or selectively perform composite vibrations in the X and Y axes. This allows the mold placed on the stage to receive multi-directional excitation, effectively disturbing the interior of the material, causing bubbles to escape from all directions, and enabling high-viscosity materials to penetrate more evenly into the complex corners and small gaps of the mold, significantly improving the quality and yield of casting.

[0065] like Figure 3 As shown, in some embodiments, the shock absorber 400 further includes a clamping member 480 and an adjusting member. The clamping member 480 is located in the upper insertion hole and abuts against one end of the clamping member 480 and the elastic member 430. The adjusting member is disposed on the upper connecting member 410 and is connected to the clamping member 480. The adjusting member is used to adjust the distance between the clamping member 480 and the vibration platform 100.

[0066] The key improvement in this embodiment is that the clamping member 480 is located inside the upper insertion hole. The clamping member 480 is a cylindrical metal part, one end of which abuts against the first end of the elastic member 430 inside the upper insertion hole. The function of the clamping member 480 is to transmit the force of the elastic member 430 to the upper connecting member 410.

[0067] An adjusting element is provided on the upper connector 410. Specifically, the adjusting element is an adjusting screw threaded onto the side wall of the upper connector 410, with its inner end extending into the upper insertion hole and connecting (or directly abutting) with the clamping element 480. By rotating the adjusting element, the clamping element 480 can be pushed or pulled back, thereby adjusting the axial position of the clamping element 480 relative to the upper connector 410 (i.e., relative to the vibration stage 100), and thus precisely adjusting the horizontal height and levelness of the vibration stage 100.

[0068] For example, the adjusting element can be a threaded adjusting screw, a worm gear mechanism, or a miniature electric actuator. The connection between the clamping element 480 and the adjusting element can be a threaded connection, a snap-fit ​​connection, or a hinge. The adjusting mechanism can also be located at the lower connecting element 420 end for adjusting the preload at the lower end.

[0069] like Figure 1 and Figure 3 As shown, in some embodiments, the adjusting member includes a screw 460 and at least two locking nuts 470. One end of the screw 460 passes through a through hole in the clamping member 480 and is connected to the clamping member 480; the other end passes through a through hole in the vibrating platform 100. At least one locking nut 470 is threaded to both ends of the screw 460, and the upper connecting member 410 and the vibrating platform 100 are clamped between two of the locking nuts 470.

[0070] The key improvement in this embodiment is that the adjusting component includes a screw 460 and at least two locking nuts 470. One end of the screw 460 passes through a through hole in the clamping member 480 and is connected to the clamping member 480 by means of a nut or welding. The other end of the screw 460 extends upward and passes through a corresponding through hole in the vibrating table 100. At least one locking nut 470 is threaded to both ends of the screw 460. Specifically, one locking nut 470 is located above the vibrating table 100, and the other is located below the upper connecting member 410.

[0071] By tightening the locking nut 470, the position of the screw 460 relative to the vibrating platform 100 can be adjusted, thereby driving the clamping member 480 to move within the upper insertion hole, changing its distance from the vibrating platform 100, and achieving precise adjustment of the horizontal height and levelness of the vibrating platform 100.

[0072] After adjustment, the two locking nuts 470 firmly clamp the upper connector 410 and the vibration platform 100 between them, forming a self-locking structure. This ensures that the adjustment state will not loosen due to vibration when the platform is working, thus guaranteeing the long-term stability and reliability of the shock absorption system.

[0073] like Figure 1 and Figure 2 As shown, in some embodiments, the vibration base 300 is provided with a guardrail 500, which extends circumferentially along the vibration base 300 and forms an opening between its two ends. The vibration platform 100 is located in the area enclosed by the guardrail 500, and the guardrail 500 is higher than the vibration platform 100. The opening allows the mold to enter and exit the vibration platform 100.

[0074] In some embodiments, this application also provides a casting production device, which includes any of the vibration platforms described in the above embodiments.
